While not quite matching last season's competition for wild unpredictability, this year's League Cup has thrown out a respectable share of shock results. Chief among those was surely Sunderland's victory over Chelsea in the quarter finals, a win which sets up this semi-final first leg tie against David Moyes's wobbly Manchester United. Further upset potential is offered up tomorrow night, as West Ham visit free-scoring Manchester City. Gwilym Mumford

The Taste9pm, Channel 4

Nigella Lawson fronts a British version of her hit US cooking competition with Anthony Bourdain and Ludo Lefebvre. Competitors must impress the judges with a single, carefully curated spoonful of their finest grub in order to become the kitchen king or cuisine queen of something or other. So it's lots of sizzling oil close-ups, hassled apron people and endless, repetitive shots of spoons going into mouths. Nigella and the camera will be friends for life, with the camera always fancying her a bit but never saying. Julia Raeside

God's Cadets: Joining The Salvation Army9pm, BBC4

A military-inspired Christian organisation, fighting suffering with love. That's how the Salvation Army see themselves, but this one-off about the army's two-year training college suggests a lot of its do-gooding is internally focused. Students and staff reflect honestly and movingly on their "calling" here. New recruit Darron and tutor Janet grapple with the idea of a God who damns their unbelieving loved ones, while abused Annmarie notes how the army often comes to the aid of its own charges.

Longmire9pm, 5USA

As Sherlock shows, taking well-trodden tales into new environments can provide an unexpected injection of adrenaline. Longmire – first seen on TCM – attempts a similar makeover for the western, following widower and county sheriff Walt Longmire as he returns to his outpost nursing a bruised psyche, and taking on a tricky murder investigation and impending re-election campaign. If this pilot is anything to go by, fears of Longmire being Justified's sleepier sibling are eased by Robert Taylor's captivating portrayal of the laconic lawman. Mark Jones

Incredibly Small World9pm, National Geographic

Dwarves, inexplicably, still seem to be a legitimate form of entertainment in themselves, which leaves "little people" with a dilemma: to embrace their spectacle status, or try to succeed conventionally. In the double-bill opener of this series about dwarves around the world, we meet some attempting the latter, but also many who've made a career from their size: Austin Powers star Verne Troyer, Colombian bull-fighting "matadwarves" and Jyoti Amge, whose smallest woman world record has made her a celebrity in India.

Later episodes will look at Whitney Houston and Anna Nicole Smith. Bim Adewunmi

Secrets Of The Body Clock With Terry Wogan10.35pm, BBC1

Old Tezza knows a thing or two about the body clock and here he comes to share them. "You'll be amazed what I've been finding out," he chirrups, confessing he's a "semi-lark" who doesn't mind getting up early. In summary: have sex first thing, pop out a baby in the morning and don't drink at lunchtime. Oh, and you're more likely to die at night. It's all delivered with trademark Wogan cheeriness, but not exactly riveting stuff. Nodding off halfway through? There goes that pesky body clock … Hannah Verdier
